osx_cocoa: please test wxRegion(size_t n, const wxPoint *points, wxPolygonFillMode fillStyle)

[Stefan Csomor]

Hi everybody

I've added a scan-line polygon conversion code, could everybody using
osx_cocoa who is on trunk and uses the wxRegion constructor with a polygon
argument please update and test their code ?

if you think you run into a problem related to this change,

then change src/osx/carbon/region.cpp, line 27 to

#define OSX_USE_SCANLINES 0

and test again, if the problem goes away, then we have a regression,
please report it to me

Thanks,

STefan Csomor
